| 20080244029 | DATA PROCESSING SYSTEM - A transmission cancellation section is provided on a bus connecting a master and a slave. During a reset of the master, the transmission cancellation section blocks the bus so that an invalid command flowing on the bus does not reach the slave and executes, instead of the master stopped by the reset operation, generation of data which corresponds to an access request command already output to the slave and is to be sent to the slave and receiving of data from the slave. | 10-02-2008 |
| 20080281938 | Selecting a master node in a multi-node computer system - Selecting a master node in a multi-node computer system is described. Each node of the multi-node computer system selects a timeout value (e.g., randomly). Each node starts a timer, which is set to expire at the selected timeout value of its corresponding node. The node with the timer that expires earliest broadcasts an election message to the other nodes of the multi-node computer system, which informs the other nodes that the broadcasting node is a candidate for mastership over the multi-node computer system. The other nodes respond to the election message upon receiving it. In the absence of a refusal message from one or more of the other nodes, the candidate is established as master node in the multi-node computer system and wherein the other nodes function as slave nodes therein. | 11-13-2008 |

| 20090037553 | Configuring or Reconfiguring a Multi-Master Information Sharing Environment - Configuring an n-way multi-master information sharing topology. Adding a new node (e.g., database server) to the information sharing topology can be implemented as follows. Initially, the new node is added as a slave of a particular co-master in the information sharing topology. The objects to replicate are instantiated on the new node by propagating data from the particular co-master to the new node. Furthermore, a capture process is created on the particular co-master to send changes to the objects to the slave. Meanwhile, the co-masters continue to propagate changes to each other. To promote the slave to a master, changes to objects stored at the slave are propagated to each of the co-masters. Furthermore, changes at each of the masters are propagated to the promoted node. | 02-05-2009 |

| 20090083390 | AUTOMATIC CLUSTERING FOR SELF-ORGANIZING GRIDS - Computational grids have traditionally not scaled effectively due to administrative hurdles to resource and user participation. Most production grids are essentially multi-site supercomputer centers, rather than truly open and heterogeneous sets of resources that can join and leave dynamically, and that can provide support for an equally dynamic set of users. Large-scale grids containing individual resources with more autonomy about when and how they join and leave will require self-organizing grid middleware services that do not require centralized administrative control. Dynamic discovery of high-performance variable-size clusters of grid nodes provides an effective solution for implementation of grids. A brute force approach to the problem of identifying these “ad-hoc clusters” would require excessive overhead in terms of both message exchange and computation. Therefore, a scalable solution is provided that uses a delay-based overlay structure to organize nodes based on their proximity to one another, using a small number of delay experiments. This overlay can then be used to provide a variable-size set of promising candidate nodes than can then be used as a cluster, or tested further to improve the selection. Simulation results show that this approach results in effective clustering with acceptable overhead. | 03-26-2009 |

Otherwise, the master window streams the data to the destination within the master window. | 08-06-2009 |
| 20090287791 | SYSTEMS AND METHODS FOR AUTOMATICALLY TESTING AN APPLICATION - Systems and methods for performing automated load and usability testing via an application delivery appliance can include methods where a browser having a unique identifier is detected and a script is injected into the HTML response generated by the page displayed within the browser.

In situations where the browser is a control browser, the calling of a function associated with the link is followed by the spawning of one or more slave browsers, where each slave browser further executes the above-listed steps beginning with the execution of the injected script and ending with the calling of the function associated with the selected link. | 11-19-2009 |

| 20150127761 | APPARATUS AND METHOD FOR CLIENT-SIDE FLOW CONTROL IN A REMOTE ACCESS ENVIRONMENT - A client-side flow control mechanism for controlling the flow of messages communicated from a service to a client in a remote access system. The service, which may be a managed or unmanaged service, may communicate messages to the client where the messages include a service sequence ID (SSI).

The service compares a difference between the current SSI and CSI to a stop window value. If the difference is greater than the stop window value, transmission of messages from the service to the client is turned OFF. The client continues to send CSI acknowledgments as it processes messages. Once the difference falls below a start window value, the transmission of messages to the client is turned ON. | 05-07-2015 |
